In this communication, the surface structure of SrTiO <sub>3</sub> adjusted by introducing different mineralization agents dictates not only the corresponding size and shape but also the dielectric properties.
There is a strong interest in studying the cellular uptake of silica nanoparticles, particularly at medically relevant concentrations (ppb-ppm range) to understand their toxicology. At present, uptake analysis at these exposure levels is impeded by the high silica background concentration. Here we describe the use of…
The band offset at CdS zinc-blende (ZB)/wurtzite (WZ) heterocrystalline interface was revisited using the first principles calculations with the local density approximation (LDA), generalized gradient approximation (GGA), and Heyd-Scuseria-Ernzerhof (HSE06) hybrid functional. It was revealed that, unlike most IV, III-…
Imogolite, one of the aluminium silicates, has a nanotube structure and has been known to form gel under alkaline condition. Imogolite nanotubes were synthesized in an acidic solution with various tube lengths by controlling the aging time from 1 d to 14 d. The length of the nanotubes grew from 100 nm to several μ m a…
The tricyanomethanide ligand reduces Fe( <sc>iii</sc> ) to Fe( <sc>ii</sc> ) yielding the discrete and chain complexes.
High temperature deposition of graphene on Cu by chemical vapor deposition can be used to produce high quality films. However, these films tend to have a non-equilibrium structure, with relatively low graphene adhesion. In this study, samples of graphene grown on copper foils by high temperature CVD were post-depositi…
The adsorption of the urea molecule on the external surface of the B_{12}N_{12} nanocage was investigated using density functional theory (DFT) calculations. Adsorption of urea on the nanocage releases energies of about --23.70 to --29.50 kcal/mol with a significant NBO charge transfer from the urea to the nanocage. I…
A new optical sensor detects aqueous boric acid and phenylboronic acid in the ppb range by a simple experimental procedure.
We report a simple method for the synthesis of mesoporous aluminosilicate nanoparticles by adopting a novel concept of using TPABr as a precursor for the structure directing agent through a solvent-free physical mixing method.
Solvent and temperature dependent paramagnetism is reported for the complex [Ru(II)(bpy)2(phendione)](PF6)2 (bpy = 2,2'-bipyridine, phendione = 1,10-phenanthroline-5,6-dione), . Magnetometry, (1)H-NMR, EPR and substituent effects confirm that the paramagnetic character is localized on the phendione ligand, and arises…
Five IIB group complexes, [ZnL1Cl2] (1), {[CdL1Cl2]}2 (2), [Cd(L1)2(NO3)2]·H2O (3), [HgL1Cl2] (4), and [ZnL2Cl2] (5) [L1 = 1-[2-(6-methoxy-2-pyridylmethyl)]-2-[2-(6-methoxy-pyridyl)]benzimidazole; L2 = 2-[2-(6-methoxypyridyl)]benzimidazole] have been synthesized and structurally characterized by elemental analysis, IR…
Fully reversible photoswitching of the coordination mode of the ligand MeN4Py (1,1-di(pyridin-2-yl)-N,N'-bis(pyridin-2-yl-methyl)-ethan-1-amine) in its ruthenium(II) complex with visible light is reported. Irradiation with visible light results in dissociation of a pyridyl moiety, which is reversed by irradiation at 3…
Cellulose nanofibrils (CNFs) are nanoscale fibers of high aspect ratio that can be isolated from a wide variety of cellulosic sources, including wood and bacterial cellulose. With high strength des ...
Poly para aminophenol (PpAP)/Al 2 O 3 composite was prepared by in situ chemical polymerization of para aminophenol using ammonium persulphate as an oxidizing agent in an aqueous medium containing anionic surfactants like DBSA (dodecyl benzene sulphonic acid) and SDS (sodium dodecyl sulphate) at 0 C. The synthesized c…
A general pore-scale model was developed which mimics the electro-active layer formation process. The model was used to simulate the active material loading on battery, fuel cell and supercapacitor electrodes. The active layer was reconstructed by coating 10 8 particles with different interparticle interactions onto a…
The high adaptability of dendrimer-based contrast agents (CAs) is ideal for the reliable molecular imaging of cancerous tissues.
Iron doped hexagonal mesoporous silica (Fe-HMS) was successfully prepared by one-pot direct synthesis at ambient temperature by using dodecylamine as a templating agent. The catalyst has been characterized by various techniques including XRD, DR-UV-Vis, FTIR, SEM and N2 adsorption. The obtained material exhibits very…
Abstract—We present a broadband microwave metamaterial (MM) absorber, the unit cell of which consists of a lumped-resistor-loaded electric-inductive-capacitive (ELC) resonator and a cut-wire on the same side of a flexible polyimide substrate. In contrast to the common MM absorber, the metallic pattern layer of the pro…
The neutral and anionic Co(n)CN (n = 1-5) clusters were investigated using density functional calculations. The most stable structures of neutral and anionic Co(n)CN (n = 1-5) clusters have been identified. In these structures, the CN radical retains its integrity as a structural unit. For anionic Co(n)CN(-) (n = 1-5)…
Lipase from Candida rugosa was immobilised on a quartz surface using an azobenzene-containing, bifunctional linker, which allows deactivation of the immobilised enzyme by irradiation with visible light.
